Hydrogeologic Setting and Ground Water Flow Beneath a Section of Indian River Bay, Delaware

Abstract: The small bays along the Atlantic coast of the Delmarva Peninsula (Delaware, Maryland, and Virginia) are a valuable natural resource, and an asset for commerce and recreation. These coastal bays also are vulnerable to eutrophication from the input of excess nutrients derived from agriculture and other human activities in the watersheds. Ground water discharge may be an appreciable source of fresh water and a transport pathway for nutrients entering the bays. This paper presents results from an investigation of… Show more

“…The maximum drilling depth reached offshore was 23 m beneath the sediment surface. The approach to logging, sampling, and analysis used in this investigation was similar to that employed in a previous investigation in Delaware (Böhlke and Krantz, 2003;Bratton et al, 2004;Krantz et al, 2004). A brief description of field and laboratory methods is included here; more details are provided in Section A of the Supplemental Material (sections A.1 through A.4).…”

“…Vanek and Lee (1991) reached a comparable conclusion for the Laholm Bay in Sweden where onshore investigations were insufficient to capture the complex offshore groundwater discharge. Manheim et al (2004) and Krantz et al (2004) also used submarine resistivity surveying to map occurrences of submarine fresh groundwater in several estuaries on the east coast of the US and found a complex distribution of freshwater. Although this distribution probably could not be predicted entirely by the terrestrial geology, there was some indication that it is controlled by submerged paleodrainage systems , much like the buried channels of this study.…”

“…Freshwater base flow, transporting nitrate from terrestrial recharge areas, enters Delmarva Peninsula's coastal lagoons via both groundwater (Andres 1992;Bratton et al 2004;Krantz et al 2004;Manheim et al 2004) and overland sources that include riverine (Lung 1994;Schwartz 2003) and agricultural ditches (Schmidt et al 2007). Seasonal precipitation is variable across these coastal bays (Fig.…”
